CYJLINDl'illt- BLOCK HOLDER.

Application filed August 22, 1919.

ers. of which the 'lollor-Jino' is a speci? cation.

This invention relates to cylind r olocl holders, that is to say, it belongs in that class oi shop fixtures or appliances intended for the purpose of supporting at a w rhbench and. at u (Ol'lYGlllGllll l'ieight, the casting which comprises the cylinders oil a gasolene engine termed a cylinder loloclz. Means provided also for rotating the hlocli in the support and for clamping the block in any desired position. i

The object of this invention is the production of a cylinder hlocl: holder having parts of special construction and arrangement, whereby it is believed a particularly strong, cheap and easily operated adjustable support for the purpo stated results.

ln the accoin mnying drawings the construction of each part and the arrangement of all the parts are illustrated. Figure 1 represents this invention shown partly in vertical section longitudinally, supported by hen-ch and holdin e cylinder block. Fig.

a front view or the carrier arm or trinoular curved plate.

V Fig. is vertical *rosssection taken upon the broken. line 3-;13 of F l, and drawn upon a somewhat larger scale. l l is a top plan YlEW upon eule of drawing as in Fig. 3, showing; this in ention without the trunnion pin and carrier.

Throughout the description and drawings the some letter is used to refer to the same Considering the drawings, upon the bench A supported lose a, upon which is erected two housings l3 and Z), with cylinh icnl passages through them. The housings re arranged end to end with space C between theni e Ll. their axes in line. The spac is bridged and the tops of the housings Specification of Letters Patent.

pin G passes tl'irough the passages in the housino's and through the ring, and it will he readily ween that when the clzunping ring is drawn upwardly and held against the pin it is firmly fixed in the housings against rotation or other displacement. The pin G is secured to the hub g of the triangular can rier plate H. The form of this plate usually employed in practice is set out in Figs. 1 and 2. This form is specially applicable to the cylinder blocks of the Ford motor. lt is not intended, however, to limit this invention to the specific shape of carrier illustrated. In Fig. 2 it will be observed that the carrier ll hes a relatively wider top portion having the short cylindrical projecting portions J and j, pierced by bolt holes as set forth, and the relatively narrow lower end provided with the pin or stud 71.

The cylinder block of the Ford automobile is provided at the sides of the opening to which the conduit for the cooling water from the radiator is attached, with bolt holes such as the threaded hole K shown in Fig. l, and the screws 7.: used with this in vention are threaded to engage those holes in he Ford cylinder block. Similarly, the blocl: IJ has a flange M pierced by a number of spaced holes, with one of which the stud 7). is shown in engagement in Fig. 1.

In the operation of this invention it is desired not only that the cylinder block he supported, but, that it shall be strongly and retatively held upon the bench, in order that any necessary work may he performed upon it, and that it may be caused to assume any position convenient for the workman. It is believed to be readily discernible from Fig. 1 that, if the handle or lever (1 he turned upverdly. the clamping ring F will be lowered and the trunnion pin G may he rotated in the two housings and clamped in any ad justed position. is the pin G is secured to the carrier L, and the hloel: L to the carrier, the hlocl: is correspondingly rotated and adjusted.

Having now described this invention, and explained the mode of its operation, what 1 claim is:

1. In a cylinder block holder, the combination with a base, of housings erected upon said base and having passages through them, the suid housings being arranged with a space between them, block or table connecting the said housings at the tops thereof, a clamping rin inoyable in said space, said table for drawing the ring upwardly, a trunnion pin passing through the ring and the' passages of the housings, and a carrier attached to the pin.

2. In a cylinder block holder, the combination with a base, of housings erected upon the said base and having passages through them, the said housings being arranged with a space between them, a clamping ring movable in the said space, said ring having a vertical stem, means acting upon the housings for drawing the ring upwardly, a trunnion pin passing through the ring and the passages of the housings, and a carrier attached to the pin.

3. In a cylinder block holder, the combination with a base, of housings erected upon the base having passages through them, the said housings being arranged with a space between them, a block or table connecting the'said housings upon the top thereof, a clamping ring movable in the said space, said ring having a vertical stern passing through the table, and a lever having a cam end engaging the said stem and acting upon the table to draw the ring upwardly, a trunnion pin passing through the ring and the passages of the housings, and a carrier attached to the said pin.

4:. In a cylinder block holder,'the combination with a carrier having a relatively wider top and a narrower bottom end, the said carrier having portions at the top provided with separated bolt holes, and having a projecting pin at the said narrower end, and a trunnion pin projecting from the said carrier between its ends.

In testimony whereof I afliX my signature.

GEORGE J. S. COLLINS.
